I thought it would be a good idea to start one, below are a list of areas by identifier in Pokémon Yellow found by using the code 01XX5DD3. A few of these are glitch maps (as indicated in bold) and can be accessed when activating the code as soon as you enter through a door. Other maps are either legitimate or will crash the game. The details of the maps which crash the game can be seen by activating the code when using the Town Map however. I haven't had a chance to fully research Pokémon Red and Blue but I've found that the glitch maps accessible in Pokémon Yellow including and in between hexadecimal identifiers ED to F4 simply crash the game in Red/Blue.

When entered through an entrance/exit: Game crashes with a white screen.Name: PALLET TOWN.Town Map location: North of Indigo Plateau.Default Music: Unknown (Static overwrites previous music).Notes: This map is between identifiers 00 (Pallet Town) and 0C (Route 1), interestingly identifiers 00-0A are all towns and Saffron City is listed last in this range, even after Indigo Plateau. This might suggest that Saffron City was the last main location to be made. By being right before Route 1 this makes me think that perhaps this was once planned as a 10th town, not including the Pokémon League.

Hello. I actually identify as gender questioning, but nowadays feel more firmly that I identify as female. My sex is male but I like to express myself as female. She/her pronouns, please.

Thank you Myri for my avatar! Thank you Aeriixion for the cute sprite above! Roelof also made different variations of the sprite (which I animated).

Beyond all philosophies are the things that go best for you; what makes you feel content. It's important to always follow your heart, so unless you feel perfectly happy about it don't just follow something because it is popular, fits a style or is conventional. Sometimes you may reach a point you're not sure who you are, but as things settle I'm convinced things do work out in time.
